Background technique

At present, in laboratories, chemical plants and other occasions, distilled water is mostly produced with electric distilled water devices. In the process of preparing distilled water, tap water is usually used as cooling water, and most of these cooling water flow directly into the sewer, resulting in a large amount of waste of water resources, although some laboratories use containers to collect the condensed water flowing out of the condenser pipe outlet for use Wash other lab supplies, but collecting all of this cooling water would require a lot of water storage. A small and medium-sized chemical laboratory produces an average of several tons of cooling water every day. It is impossible to recycle all of this cooling water, and more cooling water flows directly to the sewer. In view of the shortcomings in these distilled water production processes, it is necessary to develop a fully automatic water-saving and energy-saving distilled water device, which can save water resources and electric energy while having the functions of a general water distilled device.

Contents of the invention

The tank is connected with the condensing pipe of the cooling device; the control device is a control circuit board, which is respectively connected with the liquid level controller of the steam generator, the water inlet solenoid valve and the electric heater circuit, and connected with the liquid level controller of the cooling device, semiconductor The refrigerator is connected with the water inlet solenoid valve of the nozzle, and is connected with the liquid level controller of the distilled water collecting device.

The liquid level controllers in the steam generating device, the cooling device and the distilled water collecting device all use magnetic reed liquid level sensors, with an upper liquid level magnetic reed switch and a lower liquid level magnetic reed switch inside, and an annular magnetic float on the outside. The signal output of each switch is connected to the signal input terminal of the control circuit board, and the signal output terminal of the control circuit board is connected to each electromagnetic valve; Connect, the upper end of the water storage tank is also equipped with an exhaust cover, the exhaust cover is connected with the exhaust fan through the air pipe, and the circuit of the exhaust fan is connected with the output of the control circuit board.

A water shortage liquid level magnetic reed switch is also installed at the lower end of the liquid level controller of the steam generator, and a drain valve is installed at the bottom of the steam generator.

The present invention prepares distilled water principle and process control:

1) Preparation of distilled water: The water in the steam generator is heated by the electric heater, so that the water in the steam generator reaches the boiling point, and a large amount of water vapor is generated, which is transported to the semiconductor refrigerator through the steam delivery pipe. Condensation under the effect of heat exchange, thus making distilled water.

2) Adding tap water: The water in the steam generator will decrease with the production of distilled water, and the liquid level will drop accordingly. When the liquid level drops to the lower limit level, the solenoid valve will automatically open, and the water in the water storage tank will be automatically added. In the steam generator, when the liquid level of the steam generator rises to the upper limit liquid level, the solenoid valve will automatically close, so that the steam generator can automatically replenish water; When the liquid level drops to the lower limit, the solenoid valve connected to the external water source will automatically open, and the tap water will be sprayed from the nozzle to the semiconductor refrigerator, and after heat exchange with the semiconductor refrigerator, it will reach the water storage tank , when the liquid level of the water storage tank reaches the upper limit liquid level, the solenoid valve will automatically close, so as to realize the automatic replenishment of water and preheating of the water storage tank.

3) Steam cooling adjustment: When water vapor passes through the semiconductor refrigerator, heat exchange occurs with it, and the steam condenses to obtain distilled water; the heat generated by the semiconductor refrigerator during the heat exchange process is taken away by the sprayed water, and when the semiconductor refrigerator When the temperature of the cooler is too high, when the upper limit temperature is reached, the exhaust fan will automatically start, draw in the cold air, and exchange heat with the semiconductor cooler to cool down the semiconductor cooler. When the temperature drops, the exhaust fan will automatically stop Work, so as to realize the automatic adjustment of the efficient condensation of water vapor.

4) Distilled water collection: Distilled water is automatically collected in the receiving tank. When the water level of the distilled water receiving tank rises to the upper limit level, the hydropower system of the entire distilled water device will be automatically closed, so that the distilled water produced by the distilled water device will reach the preset value. It will automatically stop working when the volume reaches a certain value.

5) Automatic protection against water and power failure: When the water is cut off, the distilled water device will produce distilled water to the maximum, until the water level in the steam generator is low to the water shortage level, the power supply system of the entire distilled water device will be automatically shut down, thereby To achieve the maximum production of distilled water; when the power is cut off, the water inlet system and control system of the distiller will be automatically shut down, so as to realize the complete automatic control of the distilled water production process.

Positive effect of the present invention:

1) Save water. The use of semiconductor refrigerators does not require water as cooling water, and all the water added to the system is used to achieve efficient and economical effects;

2) Energy saving. The system uses a semiconductor refrigerator to cool water vapor, and the heat generated is used to preheat the water in the water storage tank, so that most of the heat can be recovered and reused, thereby saving electric energy, and the effect is remarkable.

3) The control system of this system is fully automated, which realizes unattended production of distilled water and improves efficiency.
